need information about iPhone unlocking

Hello,
a friend of mine received an iPhone 5s from the US (don't know which operator yet)
what i want to know is :

-Is there any free way to unlock the phone (make it work with local sim) ?
-Why all the websites out there request money for unlocking ? and how does that work ?
-After unlocking the phone, is there a way to download and install apps for free ( like cracked games on pc) ?

thank you

  • -Is there any free way to unlock the phone (make it work with local sim) ? - No (not of i am aware of )
    -Why all the websites out there request money for unlocking ? and how does that work ? - i guess coz they have chain of people getting them do their or your job :D

    -After unlocking the phone, is there a way to download and install apps for free ( like cracked games on pc) ?- Not sure , we used to have vshare sometime back ..

    Better look for some R sim or gevey sim , it will be cheaper than getting a factory unlock but not a reliable way , of course cheaper
